Just a real quick news post this morning as I gotta skedaddle in a bit. But I thought this was a neat bit of geology! The article explains how the rate of collision between two tectonic plates caused the Andes to grow wider, not just taller. And it opens up new possibilities for estimating the lifespan and development of other mountain ranges as well. There are still some unanswered questions, but this is a neat piece of the puzzle (figuratively and literally!)

2022: The West MacDonnell Ranges, as photographed with new Mavic 2 Pro drone from Honeymoon Gap. Strike ridges of Heavitree Quartzite (~800Ma) delineate the east-west orientation of the range. They are overlain by the madly-folded formations of the Bitter Springs Group. The ranges were uplifted as part of the Alice Springs Orogeny (500Ma to 300Ma), which was unusual in that it occurred mid-continent as opposed to on a plate boundary.

I know that most of Turbid North's material doesn't sound like this but damn this song is so gorgeous.

everyone talks about pangea but where’s all the love for the rest of the supercontinents??? rodinia? gondwana? laurasia? nuna? they’re all cool too you losers

#sorry plate tectonics are fresh in my mind bc i just had a very long talk w my supervisor about a paper he's working on about supercontinent #formation over time and it was super interesting and theres actually a lot of conflict in that field of research which is also interesting #like there are some scientists who posit that plate tectonics didn't begin until the mezoproterozoic #which is only ~1 Ga #like living organisms already existed at that point #but they believe it was single-lid tectonics prior to snowball earth(like venus and io tectonics) which is WILD #anyway my supervisor thinks that's all bullshit #because. like #their data analysis methods are super biased which i agree with #like they used a 'global' database of data points but there's a bunch of hotspots and like 40% of the points are in 1 region so thats not #GLOBALLY representative yknow #and my supervisor's paper posits that the same data actually corresponds to specific orogenies and it makes a lot more sense in the timeline

Did some very basic research on the minerology of stalactites and stalagmites, because while I was pretty certain that they form primarily from calcerous material I didn't know for sure. Anyways, turns they do mostly form from calcerous material so I'm fairly confident that a primary material found in the caves near Kirkwall is limestone or dolostone (or their metamorphed counterpart) so now all I need to do is determine the sedimentary environment.

#i think for the caves at least the environment is shallow sea or other marine environment #tho isnt kirkwall surrounded by mountains #i need to revisit the cave and see if theres any evidence of orogeny structures #dragon age #dragon age 2

the thing about reading really good fantasy series w an interesting magic system is that it makes me think abt my own fantasy world and its subpar magic system that i haven't quite figured out. but maybe i can learn something from orogeny

#.txt #not that im going to steal the magic system. i wouldnt dream of it #its way too unique anyway #but. maybe i can try to think of a different approach to mine 🤔 knowing what i know of orogeny #rahhhh nk jemisin how do u do it #spare one braincell for me maybe

gd just realized this morning that in the re-re-redone outline I started on last night I messed up a side character's name 😭

#happily typing akllasisa instead of akllasumaq without a single braincell pinging in my head... #hm. I should have a tag for this series. since I ditched the old placeholder name #wip - orogeny #yeah <3

I'm almost done putting in island arcs and orogeny into my gplates simulation and I feel like my brain's about to melt out of my eye sockets

#I still need to add the laramide-style orogeny at subducted mid-ocean ridges but that should be it #And then I need to change the laramide and ural orogenies to deactivate #But other than that I'm done #!!! #I thought this day would never come #worldbuilding

2 Billion years of Tectonic History for Jom'Gol !!!!

After simulating the plate tectonics for an excruciating 2.5 billion years (not irl time, but might as well have been), I made this crude animation of the previous 2.5 billion years of tectonic history!

Although very crude, the simple borders represent landmasses, the scratchy lines represent orogeny or mountain ranges. Every frame is 50 million years (date listed at the top). (also little sounds in there too .w.)

I intend to add an additional space in between each frame for every 25 million years, then probably color them with a basic topographic map. Until then !!! I continue on !!!!

SCIENCE SATURDAY: URANIUM

Did you know that the Morrison Formation is known for more than just dinosaur bones? Between 1947 and 1983 it yielded 419,489,000 pounds of uranium oxide. That's 51% of our uranium ore.

Most of this ore has been mined from my home state of New Mexico.

Broken up into members (I will explain what those are on Wednesday so tune in!), the Westwater Canyon, and Jackpile Sandstone have the highest uranium ore production. However, the Salt Wash Member that I currently work in is not far behind. Don't worry, I grew up camping in the uranium ore-filled mountains and there's been no lasting effects.

So how did all that uranium end up in the Morrison rocks? Groundwater movement during deposition of the sandstones, usually by low-temp hydrothermal processes.

During the late Jurassic, the Sevier Orogeny (mountain building) was in full swing. Not far from our Morrison Basin was a chain of volcanic mountains similar to the Cascades and it dumped a lot of ash and there was a lot of hydrothermal activity.

*genuinely curious* Why do you love mountains so much?

i've honestly wondered this myself for many years, and there are definitely some inciting incidents—i did semi-pro downhill skiing as a kid before my fucked up body came to get me and time spend in the mountains with my dad was some of the only good, genuinely joyous time i ever had in an otherwise tumultuous and difficult childhood. i saw david brashears's (may his memory be a blessing) film EVEREST (1998) when it was released in imax probably at least half a dozen different times. i had my childhood period of obsession with arctic and high alpine disasters.

if i had to pick a single inciting incident, though, it would be when i went on a family grave tour trip in the most true ashkenazi jew fashion to germany when i was 8. we went all over bavaria to visit graveyards to clean and visit the memorials of our relatives lost in the shoah and then, to be slightly less depressing for the four kids, we went to switzerland for two weeks and stayed in a very small mountain tourist town. on that trip, we rode cable cars all around the alps, and took the train to jungfraujoch.

i was, to put it simply, obsessed. and i've never stopped being obsessed at any point since, although that obsession has waxed and waned in any given year.

there's something about mountains, the obvious titanic forces of orogeny inherent in their rise, their beauty, how little they care about humans while still being central to our world and many of our belief systems. humans are willing to put themselves through almost unimaginable degrees of torture and pain to climb mountains, to study mountains. they last so long they eclipse our sense of even the deepest time.

so essentially i don't really know why im so obsessed with mountains, but i am, and pretty much always have been, but part of it was definitely formed by spending part of a summer in switzerland as a kid.
